Objective:To explore the value of virtual touch tissue quantification(VTQ)technology in evaluating the change of thyroid's stiffness with connective tissue diseases(CTD).Methods:A total of 45 patients with CTD and 30 healthy volunteers were measured the SWV of both thyroid lateral lobe using VTQ technology.Study the correlation between the SWV of thyroid and the course of disease,the levels of ESR and CRP.Results:The SWV for case group(2.30±0.46)m/s was higher than that for controls(1.85±0.20)m/s,the differ...
